Which of the following is true when comparing an uncatalyzed reaction to the same reaction with a catalyst?
a) the catalyzed reaction will be slower.
b) the catalyzed reaction will have the same â†g.
c) the catalyzed reaction will have higher activation energy.
d) the catalyzed reaction will consume all of the catalyst.

B) The catalyzed reaction will have the same ΔG.

Explanation:

Catalysts are molecules that speed up chemical reactions.They increase the rate of chemical reactions such that the rate at which reactants are converted to products increases.Catalysts increase the rate of reaction by lowering the activation energy of the reactants.Activation energy refers to the minimum energy required by the reactants for a reaction to occur.Therefore, the rate of catalyzed reactions will be higher due to a decrease in the activation energy of the reactants.However, catalysts do not affect delta G of a reaction and thus, delta G of an uncatalyzed reaction is the same as that of a catalyzed reaction.
